UNITED STATES PATENT OFFICE.

MUSIC-LEAF TURNER.

SPECIFICATION f0 g part of Letters Patent No. 236,345, dated January 4, 1881.

Application filed August 17. 1850. (Model) To all whom it may concern Be it known that I, Framers J. LIPPITI, a citizen of the United States, resident at Vasilington, in the county of \Vashington and District of Columbia, have invented certain new and useful Improvements in Leaf-Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdmwtags, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention has relation to leaf-tnrners for music-racks; and it consists of the features of construction and combination hereinafter fully described, and particularly pointed out in the claims.

Figure 1 is a front view of a device embodying the improvements in my invention, showing the parts in their normal position-that is, prior to operating the pedal to turn the leaf. Fig. 2 is a front view, showing the parts after the pedal has been operated to turn a leaf. Fig. 3 is a rear elevation, showing the parts in the position shown in Fig. 1. Fig. 4 is a rear elevation,the parts being in theposition shown in Fig. 2. Fig. 5 is a plan view. Fig. 6 is a a bottom-plan view. Fig. 7 is a side elevation. Fig. 8 is a detail view of the removable cam-lever by which the arms for turning the leaves are operated. Fig. 9 is a view of the clamp for tempomrily binding the sheets in the rack, said clamp being shown in an open position; and Fig. 10 is a detail, in section, of the finger-pieces and ring for holding the clam p open.

Referring by letter to the drawings, A designates the frame which supports the operating parts of the leaf-turner, and which is designed to be attached to a piano or organ or to a standard, and the operating-leverconnected by a wire to a pedal pivoted to the instrument or standard in convenient reach of the operator.

B designates a clamp the jaw C of which is pivoted to a vertical rod, 0, at the middle of the frame A, and is operated by springs D to return it to and hold it in a normal position to clamp the sheets of music, which are first slipped on the pins D, secured to one of the jaws,and passing through holes D in theother, between the jaws. The jaws O are provided at: their rear edges with finger-pieces E E, the prece E carrying a ring, E, which, when the pieces are pressed together, is to he slipped over the piece E, to hold the jaws open to permit the insertion or removal of the musicsheets.

To the top of the frame A, about centrally of the same,and at the rearthereof, is secureda recessed standard, F. The recesses F are made horizontally in the front face of the standard F, and in each one of them is pivoted a rectangular wire arm, F, extending first; horizontally and then downward, as shown.

In the rear of the standard F is secured a vertical shaft, G, to the lower end of which is pivoted one end of a flat plate, G. The opposite end of the flat plate G is provided with a series of perforations, and is connected by a spiral retracting-spring, G, to the rear face of the upper cross-piece of the frame A, so that it will be retracted toward the left side of the frame. The pivoted plate G also carries a vertical shaft, H, which extends slightly above the recessed standard F, and describes the arc of a circle around the vertical shaft G when the plate G is turned on its pivot.

To thea-ight of the recessed standard F is secured a vertical stop, H", against which the cam-lever H stops in its backward movement. The base of the cam-lever H has a bearing, H provided with a fixed internal sleeve to enlarge the bearing, and an opening, H, in the rear of the bearing H The upper end of the shaft G enters the bearing H and the upper end of the vertical shaft H enters the opening H. The arm H of the cam-lever H curves forward to the right of the vertical standard F, and comes between it and the stop H. The forward end of the curved arm extends outwardly to the right, and is provided with a shoulder, I, on its under face, and terminates in a flat or blade point, I. A hanger, 1, depends from the top of and at the right of the center of the frame, and in this hanger is pivoted a perforated rockinglever, P, and at the center of the lever P is secured an inclined arm, I. The upper end of the inclined arm I is perforated, and is connected by a rod, J, with the outer end of the pivoted plate G. The inner end of the rocklever l is connected by a catgut, J, leading through a slot in the lower cross-piece of the frame, with the arm J of a rock-shaft, J working in hearings on the under side of the frame. The rock-shaft J has arms K K K, which curve outward and upward in frontof the frame, and have a guard or rail, K, at their outer ends, which is bent outward and downward at L. The rock-shaft J 3 is provided with a retracting-spring, L, which has a tendency to hold the guard K up against the sheets of music when in place in the rack.

A stud or short arm, M, extends forward between the rock-shaft J and the under face of the lower cross-piece of the frame A, and has pivoted upon its outer end a curved finger, M, curved outward, as shown at M, and extending to the right, where it is curved slightly upward, then downward and outward, as shown in Fig.1. This finger M is provided with an arm, N, at itsinner end, which extends first horizontally to the left and then upward, where it is provided with a stop, X.

The rock-shaft J is provided with an arm, P, which, when carried forward and downward, strikes in a notch, N, in the horizontal portion of the arm X, turns the arm N down until the arm P on the rock-shaft strikes the stop S on the arm N, which operation will have caused the finger M to turn to point to the left of the frame. A retmeting-spring, Q, on the stud M connects with the finger M'and carries it back to its normal position. A red or wire, Q, connects the outer end of the rocking lever P with the treadlc on the instrument or standard, as the case may be.

The sheets of music having been inserted into the clamp, the arms P are placed under the leaf each is to turn, the uppermost ar'm F being under the uppermost leaf, and so on 2 throughout the series. The lower ends of the sheets are held in place by a spring, X, and are at the right of the center of the frame. The cam-lever H is then put in place on the shafts G and H and the curved arm brought over the uppermost arm F of the series. By depressing the pedal the rodQ will dmwupon the outer end of the rocking lever I, which will carry the inclined arm 1 to the right and carry the pivoted plate G, which is connected with the inclined ann, to the right. The pivoted plate G carries the vertical shaft H i around and causes the cam-lever H to operate and push the uppermost arm F and cause it to turn the upper portion of the sheet. While this is being done the inner end of the rocking lever l is moved upward, and, through the catgut J, draws upon the arm J of the rockshaft J, musing the arms and guard K to be drawn down out of the way of the turning leaf, and, through the arm P of the rock-shaft, operates the finger M to strike the lower part of the leaf on the righthand face or back of i the same just in time to carry it overand restdown upon and hold it in place until the arms F. The arm of the cam-lever strikes the vertical stop H and the cam-lever slides down to the next arm F, and thus on till they have all been turned to the left side of the frame, when the cam-lever should be removed from its vertical shafts and the arms turned back to the right and the cam-lever placed again upon the uppermostarm F, to again permit the leaves to be turned to the left. The finger M, after the leaves have all been turned to the left, may be forced down and caught under the bearing at the left of the frame, to be out of the way while turning the leaves back, and to also lock the guard K down out of the way.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a music leaf-turner, therecessed standard F, provided with the pivoted arms F, the vertical shaft G, and thepivoted plate G',car rying the vertical shaft [1, in combination with the cam-lever H, adapted to slide upon the shafts G and H and to operate the arms F, the retracting-spring G and the rocking lever I, carrying the arm I, constructed and operating substantially as set forth.

2. In a leaf-turner for mnsiemcks, the rocking shaft J working in bearings at the lower side of the frame A, and provided with the guard K. constructed substantially as described, in combination with the rocking lever 1 for the purposes set forth.

3- In a leaf-turner, the rock shaft J pro vided with the arm 1 and the guard K, in combination with the finger )l', constructed as described, and provided with the arm X, having notch X and stop X, the n-tmctingsprings L and Q, catgut J, and rocking lever I, constructed and operating substantially as and for the purposes set forth.

4. In a leaf-turner, the combination of the cam-lever l1 upon the shafts G and H, with the stop H and the pivoted arms F, substantially as and for the purposes set forth.

5. In a leaf-tumer, the combination. with the pivoted arms F, of the vertical shaft G, having the pivoted plate G at its lower end, on which is mounted the vertical shaft H, and the cam-lever IF, having the bearing H. and opening H, the curved arm H, and the bladepoint I' and shoulder l, constructed and operating substantially as and for the purposes set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
